Specification of Letters Patent.

Patented July 13, 1915.

Application filed September 3, 1913, Serial No. 787,833. Renewed May 3,1915. Serial No. 25,630.

To all whom it may concern:

Be it known that I, HENRY PONGRAT, a citizen of the United States ofAmerica, and resident of Canal Dover, county of Ti1scarawas, and Stateof Ohio, have invented certain new and useful Improvements in Feed-Water Valves for Boilers, of which the following is a specification.

This invention relates broadly to a water feed valve for boilers andspecifically to a double feed apparatus for boilers.

The primary object of the invention is to provide a simple andconvenient valve through which water may be delivered to a boiler,dispensing with the usual two lines of feed pipe with the series ofvalves employed therein.

A further object is to provide a double feed apparatus through whichwater may be delivered to the boiler in either of two ways, each havingtherein a single check valve, one of said ways being wholly closed whenthe other is in operation, thus affording ready access for the removalof the check valve and for grinding the valve-seat in one of said wayswithout interfering with the feed through the other of said ways.

A still further object is to provide a valve of the character mentionedwhich may be operated to wholly cut off the passage of watertherethrough, and having means whereby it may be locked against movementfrom the cut-off position for afiording an element of safety in caseswhere it is necessary for an attendant to enter the boiler.

With these and other objects in view, the invention resides in thefeatures of construction, arrangement of parts and combinations ofelements which will hereinafter be exemplified, reference being had tothe accompanying drawings, forming a part of this specification, inwhich Figure 1 is a front elevation of the invention; Fig. 2 is a sideelevation ofthe same; Fig. 3 is a top plan view; Fig. 1 is asubstantially central vertical section; Fig. 5 is a transversehorizontal section'on the line 55, Fig. 1; Fig. 6 is a similar sectionon the line 66, Fig. 4,; and Fig. 7 is a detail view, reduced,illustrating the locking means.

Referring to said drawings, in which like designating charactersdistinguish like parts throughout the several views- 1 indicates acentral body portion havlng two similar upright arms 2 and 3 disposed onopposite sides thereof and integral therewith. Said body is supported bya pair of f oppositely disposed integral outwardly' curved legs 4: and 5which project upward from an integral flanged base 6 which is adaptedfor mounting on a boiler at a suitable point.

Extending vertically through the body 1 is a large central bore having aslight downward taper and within which is seated acorrespondingly-tapered cone 7 which constitutes a rotatable valve, aground joint being formed between said body and said cone. A threadedstem 8 is formed on the lower end of said cone, and threaded thereonagainst a metal washer 9, having integral therewith a plurality ofupwardly and outwardly curved flexible fingers 9, is an adjusting nut10, said fingers being seated in recesses 11 provided therefor in theunder face of a washer 12 which is fitted upon a non-circular portion 7at the lower end of said cone 7. From this it will be apparent that thecone 7 is held in a downwardly drawn seated position under ayielding'tension, and that said cone may be adjusted by tightening ofthe nut 10 from time to time to compensate for wear. It will further beseen that, owing to the washer 12 being non-rotatable on the portion 7of the cone, the said washer 12, washer 9 and nut 10 follow the conewhen the latter is rotated in either direction, chance rotation of thenut with respect to the stem being thus guarded against.

Provided in the cone 7 are two ai-cuately curved cored-out passages 13and 14, the opposite ends of each of which open through the face of thecone at a spaced distance apart and in substantially the same verticalline. Formed on the front side of the body 1 is an outstanding tubulararm 15 adapted for connection to a water supply pipe, as 16, the passage17 through said arm communicating with a passage 18 provided in the wallof said body, the last mentioned passage having two separate outlets 18and 18 which open at spaced distances apart into the large central borein which the cone 7 is mounted.

In one position of the cone 7, as is shown most clearly in Figs. 4t and5, the outlet 18 is closed against the passage of water, while.

the outlet 18 registers with the upper part of the passage 13 in thecone. In said position the lower part of said passage 13 registers witha curved passage 19 leading outward through the body 1 and upward intothe arm 3 where it communicates with a valve chamber 20 provided in saidarm. Threaded vertically into a socket provided therefor in the bottomof the chamber 20 is a tubular member 21 having a valve seat 22 formedat its upper end, and vertically movable within said member are theguide-legs 23 of a check valve24= which normally seats by gravity, or byreturn water pressure, upon the seat 22. Said tubular member 21 andvalve 2 1 are introduced in their work ing positions through a verticalopening in the upper end of the arm 3 which is thereafter closed by athreaded cap 25.

Leading inward from the valve chamber 20 through the body 1 is a passage26 which, when the cone occupies the position shown in Figs. 4, 5 and 6,registers with the upper part of the passage 1 1 in said cone. The lowerpart of said passage 14: at the same time registers with the end of apassage 27 .which leads downward through the leg 5 and communicatesthrough a port 28 in the base 6 with the interior of the boiler uponwhich said base is mounted.

From the foregoing it will be seen that, when the cone occupies theposition shown in Figs. 1, 5 and 6, water entering through the supplypipe 16 traverses a circuitous course, passing through passage 17 in arm15, thence through outlet 18 of passage 18 to and through passage 13 inthe cone 7 thence through passage 19 in the body 1 and the arm 3 to andthrough the interior of member 21, and, forcing the check valve 2st offits seat, passes into the valve chamber 20, whence it passes throughpassage 26 to and through passage 141 in the cone 7, thence through.passage 27 in leg 5, and to the boiler through port 28.

Vfhen the check-valve 2 1 or its seat require attention, as when wearoccurs, the cone 7 is turned or rotated in the direction indicated bythe arrow in Fig. 3 to the position indicated in dotted lines in saidfigure, the lever 29 pivotally mounted between a pair of upright lugs 30on the cone being employed for effecting the rotation. This action cutsoff the water supply through the passages in the arm 3, leg 5 and rightside of the body 1 and brings the passages 13 and 14 in the cone intoregister with passages in the arm 2, leg 1 and left side of said body,the last mentioned passages being substantially identical with those onthe opposite side. The flow of water from the supply pipe then passesthrough passage 17 in arm 15, thence through outlet 18 of passage 18 toand through passage 1 1 in cone 7, thence through passage 19' in thebody 1 and the arm 2 'to and through the interior of member 21, and,forcing the check valve 2 1 off its seat, passes into the valve chamber20, whence it passes through passage 26 to and through passage 13 in thecone 7, thence through passage 27 in leg 1-, and to the boiler throughport 28.

As is obvious, when the cone 7 occupies the last above describedposition, access may readily be had to the valve chamber 20 for removingthe check valve 2a or for grinding valve-seat 22, removal of the cap 25only being necessary. Likewise, when the cone occupies the first above.described position, access may be had to valve 2-1 and valveseat 22 byremoval of cap 25.

For enabling the proper positions of the cone 7 to be accuratelygagedthat is, for marking the limit of movement required to cause thepassages 13 and 1st to accurately register with the passages in the body1 stop-shoulders or lips 31 and 32 are provided on the top of the body 1adapted to be respectively engaged by the heads 33 and 3% of smallscrews directed into the side of the cone 7 when the proper limits ofrotary movement have been reached.

When it is desired tocut off the passage of water to the boiler, thevalve cone 7 is rotated to any intermediate position wherein theopenings of passages 13 and 1st fail to register with the water passagesin the body 1. To look said cone in cut-off position, the same is turnedto a position wherein the lever 29 stands at substantially a right angleto a line connecting the arms 2 and 3, after which a pin 35 whichnormally overlies said lever, as shown in Figs. 1, 2 and 3, is withdrawnfrom a pair of upright lugs 36 between which the body of said levernormally lies, and said lever body is elevated to the position shown indotted lines in Fig. 7, whereupon the pin 35 is replaced so as to occupyunderlying relation to said lever body. In this position a downturnednose 37 formed on the front end of said lever seats in a socket 338provided therefor in a projection 39 formed on the front face of thebody 1; and, as is apparent, rotation of the valve cone '7 with respectto said body is thus effectually prevented. To prevent unauthorizedlowering of said lever from its elevated cone-locking position, a smallpadlock, as 40, shown in Fig. 7, may have its hasp projected through anopening or slottl provided in the pointed end of the pin 35.

From the foregoing it will be understood that the check-valves 24c andtubular mem: bers 21, the latter having the check-valve seats formedthereon, constitute practically all the parts which are 'subjectedtoundue wear under the action of the water; and further that access may bereadily had to said parts for repair or renewal without cutting ofi' thefeed of water to the boiler.

The passages through which the water courses in passing through thedevice have no abrupt turns or bends therein which act to unduly retardthe passage of the water, and no abrupt shoulders or ledges arepresented which are liable to retard the Water or to become worn by theaction of the latter.

Provided in an annular flange 42 carried by each tubular member 21 areoppositely disposed recesses 43 adapted to receive the prongs of aninstrument whereby said member is threaded to and from its seat.

Each of the check-valves 24 and 24: presents an annular fiat shoulder44: to the jet of water which is forcibly directed against the face ofthe valve from between the guiding portion of the latter and the wallsof the tubular member 21. Thus, the inclined portion of the valve-facedoes not receive thereagainst the full force of the entering water, andsaid face is therefore not subjected to the wearing action of the waterto the same extent as would be the case if said inclined portion wereextended entirely to said guiding portion.
